The pics and component list were invaluable.

I have a acer aspire 7720g for the last month the colour on my LCD as been going fuzzy like one of
those weird sixty's films. Sometimes it last a few minuets or for hours, turning off the computer helps sometimes for that moment and other times it takes a lot of turning it on and off to get it to work there seams no logic to it since the next day or week when I turn it on its still fuzzy and if left on for a while the screen clears up.How can I fix it.I Ivan,

I have a problem with a LCD monitor Samsung SA850.
At power on , appear on LCD some strange random horizontal lines on the right part of LCD.
like this http://imageshack.us/photo/my-images/825/tbwb.jpg
After 30 minutes with power on, lines disappear and monitor work normal.
Power supply is a 14V/4.5A - is like a laptop power supply.
In the all ports: DVI, HDMI, VGA - problem is the same.
I change the cables, video card - same problem.
Could be the external power supply ?
Thanks !Hi Ivan !

Dr. IvanTue, 13 Aug 2013 20:51:40 +0000http://blog.dr-ivan.com/?p=640#comment-53899Hi Gabriel!
This sounds perhaps like a recurring problem either due to heat (damaging newly replaced components), or perhaps poor grounding for one reason or the other (and in the latter case I would strongly advise touching it at all, far less disassembling it). In any case you could try to see wether there are any heat spots on the back panel, remove anything that might be covering the ventilation holes, move the TV away from the wall to increase air circulation. Failing that, you could always get a fan pointing at the back panel to try to cool it to see if it helps.
Hope any of these suggestions help!

gabrielSun, 11 Aug 2013 23:53:54 +0000http://blog.dr-ivan.com/?p=640#comment-53797Hi dr-ivan! ;)
I have a samsung LCD about 3 years old, and would love to have some help diagnosing it :)
Here's the deal: the tv restarts randomly (mostly between commercials - if I open the receivers menu, it doesn't happen at all, and I can wait watching the commercials in a small portion of the screen). Sometimes it will keep cycling on/off with the red led blinking, trying to get on (the back light lits up), sometimes dies completely until someone pulls the power plug and places it again (AND in this case, sometimes you need to wait a couple minutes with the cable unplugged to escape the on/off cycle and start the tv correctly). No funny clicking noises, I believe the relay is a "quiet" type, I only hear the melody, even when it was new.
A month ago, I opened it and the capacitors were all good (at a first glance). Replaced about 5 of them near a heat sink, should they be bad. TV ran great during commercials for a couple of days, then got the same as before. Opened it again and replaced ALL of the remaining electrolitic capacitors (except the very large fellow). Ran fine for a couple of days, then back on the same pain... I have electronics background, but would appreciate any ideas on what the problem could be, since on the web I only find capacitor-related posts...
Many thanks for the help :D
